I have a question for the forum. I have seen a problem in my 2004 F150 4 wheel drive. When it was very cold outside, when I start the truck and start moving, I heard a clicking sound from the front wheels. When I moved the 4 wheel drive selector to 4 wheel high it stopped and then back to 2 wheel high it started again. If I left it in 4 wheel high for a while (while it warmed) then the noise stopped. Anyone ever have this problem? Everytime I would take to yo get it serviced, the dealer could not hear the noise since the truck had been driven. It is still under warranty and I want to get it fixed soon. Thanks for any help
